Important Router Table Requirements

Router tables are not commonly used with guide bushings because either a bearing or fence is used. The Leigh eBush system is designed around the decades-old Porter Cable/Black & Decker industry standard. If you do not already have tha router table plate that accepts the Porter Cable-style guide bushings, then you will need to adapt your current model or purchase a plate that accepts these bushings.
